Towards an enhanced protection of attached boundary layers in hybrid RANS/LES methods [PDF]
Journal of Computational Physics, 2020 Abstract A robust strategy for the RANS shielding of attached boundary layers in a hybrid RANS/LES context is presented, addressing two major issues. Firstly, the attached boundary layers must be detected to ensure their RANS treatment, but the original shielding function used by automatic methods such as DDES (2006) or ZDES mode 2 (2012) fails for ...

Hybrid RANS/LES of plane impinging jets with k-omega based models [PDF]
, 2010 Plane impinging jets with nozzle-plate distances H/B=10 at Re=13500 and H/B=9.2 at Re=20000 are simulated with k-omega based hybrid RANS/LES models. Three ways of substitution of the turbulent length scale by the local grid size in the LES mode of the ...

Simulation Uncertainty for a Virtual Ultrasonic Flow Meter
Metrology, 2022 Ultrasonic clamp-on meters have become an established technology for non-invasive flow measurements. Under disturbed flow conditions, their measurement values must be adjusted with corresponding fluid mechanical calibration factors. Due to the variety of
